The short answer is yes, for both mom and baby girls.
How much does it reduce the risk is more debatable. It also reduces the risk of ovarian and possibly endometrial cancers as well. In f act pregnancy itself may help reduce the risks of these also. Here are a couple of studies from reputable journals that demonstrated reduction in breast cancer risk for women that breast fed: if women who do not breastfeed or who breastfed for less than 3 months were to do so for 4 to 12 months, breast cancer among parous premenopausal women could be reduce by 11%; if all women with children lactated for 24 months or longer, the incidence might be reduced by nearly 25%. Source: newcomb, p. Etal. "lactation and reduced risk of premenopausal breast cancer." n engl j med 1994; 330(2):81-87. Women who were breastfed as infants, even if only for a short time, showed an approximate 25% lower risk of developing premenopausal or postmenopausal breast cancer, compared to women who were bottle-fed as an infant.
